[0032] The invention provides an air chamber structure and pulp molding equipment which can effectively reduce production costs.

[0033] Combine the following Figure 1 to Figure 4 The technical solution provided by the present invention is described in more detail.

[0034] The present invention provides an air chamber structure, comprising:

[0035] A structural body 100, wherein a main air chamber 110 is disposed in the structural body 100;

[0036] A partition inner wall 140, which is an annular structure and is disposed in the main air chamber 110 to divide the main air chamber 110 into a first air chamber 170 and a second air chamber 180 of an annular structure, and a gas channel 200 communicating with the first air chamber 170 is disposed on the structural body 100;

[0037] A conducting structure is disposed on the partition inner wall 140 , and the conducting structure is used to conduct or block the first air chamber 170 and the second air chamber 180 of the annular structure.

[0038] The air chamber structure provided by the present invention comprises a structural body 100 and a partition inner wall 140, wherein the partition inner wall 140 is an annular structure, and the partition inner wall 140 divides the main air chamber 110 in the structural body 100 into a first air chamber 170 and a second air chamber 180 of an annular structure, and a gas channel 200 connected to the first air chamber 170 is arranged on the structural body 100; a conducting structure is arranged on the partition inner wall 140, and the conducting structure is used to conduct or block the first air chamber 170 and the second air chamber 180 of the annular structure. When the conducting structure blocks the first air chamber 170 and the annular structure When the conducting structure conducts the first air chamber 170 and the second air chamber 180 of the annular structure, the gas channel 200 is connected to the first air chamber 170, and the first air chamber 170 is used to cooperate with the mold adapted thereto; when the conducting structure conducts the first air chamber 170 and the second air chamber 180 of the annular structure, the first air chamber 170 and the second air chamber 180 of the annular structure are connected, and the main air chamber 110 is a completely connected air chamber structure, and the gas channel 200 is connected to the first air chamber 170, which can be used to cooperate with the mold adapted to the main air chamber 110, so that it can be suitable for the production needs of molds of different sizes, effectively reducing the production cost.

[0039] It should be noted that the partition inner wall 140 is arranged in the main air chamber 110, the first air chamber 170 is formed by enclosing the partition inner wall 140, and the second air chamber 180 of the annular structure is the part of the main air chamber 110 located outside the partition inner wall 140. The first air chamber 170 and the second air chamber 180 of the annular structure are respectively located on the inner and outer sides of the partition inner wall 140. By providing a conducting structure on the partition inner wall 140, the size of the air chamber can be changed, so that it can be suitable for molds of different sizes as needed to reduce production costs.

[0040] It is understandable that, since the mold is connected to the air chamber, each product station on the mold needs to be connected to the air chamber to ensure that each product can contact the air chamber and ensure the transfer reliability of the product.

[0041] When the conducting structure blocks the first air chamber 170 and the second air chamber 180 of the annular structure, the gas channel 200 is connected to the first air chamber 170, and the first air chamber 170 is used to cooperate with a mold that is compatible with it. It should be understood that the size of the mold is compatible with the partition inner wall 140, and the mold can be fixed on the partition inner wall 140; or, the mold can be fixed on the structural body 100, but the size of the air chamber required by the mold is compatible with the first air chamber 170.

[0042] For example, when the size of the main structure is 1100mm*1100mm and the size of the first air chamber 170 is 950mm*950mm, the size of the mold is 1100mm*1100mm or 950mm*950mm or 1100*950mm.

[0043] In some embodiments of the present invention, the first air chamber 170 and the second air chamber 180 may also be arranged side by side.

[0044] Alternatively, the second air chamber 180 is disposed on both sides or around the first air chamber 170, and a conducting structure is disposed between the first air chamber 170 and the second air chamber 180. The first air chamber 170 alone is used in conjunction with a mold adapted thereto; the first air chamber 170 and two second air chambers 180 in the same row may form a whole and be used in conjunction with a mold adapted thereto; or the first air chamber 170 and two second air chambers 180 in the same column may form a whole and be used in conjunction with a mold adapted thereto; or the first air chamber 170 and one second air chamber 180 in the same row may form a whole and be used in conjunction with a mold adapted thereto.

By installing the quick-release structure, the first air chamber 170 and the second air chamber 180 of the annular structure can be blocked.

[0047] In some embodiments of the present invention, the partition inner wall 140 includes a fixed wall 150 and a quick-release wall 160 , and the quick-release wall 160 is detachably connected between two adjacent fixed walls 150 to form an annular structure.

[0048] In some of the above embodiments of the present invention, the partition inner wall 140 is detachably connected by a fixed wall 150 and a quick-release wall 160 to form an annular structure, and the quick-release wall 160 is detachably connected between two adjacent fixed walls 150. When it is necessary to conduct the first air chamber 170 and the second air chamber 180 of the annular structure, the quick-release wall 160 can be removed to achieve conduction. When it is necessary to block the first air chamber 170 and the second air chamber 180 of the annular structure, the quick-release wall 160 can be installed to achieve blocking. The structure is simple and easy to adjust according to the mold size, which is very convenient.

[0049] In some embodiments of the present invention, the fixed wall 150 is an L-shaped structure, the four quick-release walls 160 are straight walls, the four fixed walls 150 are respectively arranged at four corner positions, and the four quick-release walls 160 are respectively connected between two adjacent fixed walls 150 to form a square ring structure.

[0050] In some of the above embodiments of the present invention, the fixed wall 150 is an L-shaped structure, and four of the fixed walls 150 and the quick-release walls 160 are provided, and the four fixed walls 150 are respectively provided at four corner positions, and the four quick-release walls 160 are provided between two adjacent fixed walls 150 to form a square ring structure. When it is necessary to conduct the first air chamber 170 and the second air chamber 180 of the ring structure, the quick-release wall 160 can be removed to achieve conduction. When it is necessary to block the first air chamber 170 and the second air chamber 180 of the ring structure, the quick-release wall 160 can be installed to achieve blocking. The structure is simple and easy to adjust according to the mold size, which is very convenient.

[0051] Furthermore, the four quick-release walls 160 form a rectangular array distribution structure, which can better ensure the uniformity of the air pressure inside the air chamber when the first air chamber 170 and the second air chamber 180 of the annular structure are connected, and further ensure normal product transfer.

[0052] It is understandable that the partition inner wall 140 may also be a circular ring structure or other annular structures; the main air chamber 110 may be a square structure or a circular structure or other shapes of structures.

[0053] In some embodiments of the present invention, extension portions 240 are provided at both ends of the quick-release wall 160, and matching portions 250 are provided on two adjacent fixed walls 150. The extension portions 240 and the matching portions 250 cooperate with each other to make the quick-release wall 160 and the fixed wall 150 detachably connected.

[0054] In some of the above embodiments of the present invention, the quick-release wall 160 and the fixed wall 150 are detachably connected by the cooperation of the extension portion 240 and the matching portion 250 .

[0055] Specifically, the extension portion 240 is a protrusion disposed at both ends of the quick-release wall 160 , and the matching portion 250 is a groove disposed at both ends of the fixed wall 150 . The protrusion and the groove cooperate to achieve a detachable connection between the quick-release wall 160 and the fixed wall 150 .

[0059] In some of the above embodiments of the present invention, a plurality of support blocks 230 are disposed in the first air chamber 170 , and the plurality of support blocks 230 are used to support the mold above the air chamber structure to ensure the connection reliability between the mold and the air chamber structure.

[0060] It should be noted that the setting of the support block 230 will not affect the contact between the product in the mold and the air chamber, and the support block 230 will not affect the gas circulation in the air chamber structure, ensuring that the air chamber structure can be quickly in a negative pressure state and ensuring that the product can be transferred smoothly.

[0061] It can be understood that the plurality of support blocks 230 are arranged in a matrix structure in the first air chamber 170, and the plurality of support blocks 230 are spaced apart and arranged in multiple rows, and the multiple rows are parallel to each other, thereby ensuring that there is a path for gas circulation between any two of the support blocks 230, ensuring that the air chamber structure can quickly be in a negative pressure state.

[0062] In some embodiments of the present invention, the structural body 100 includes an air chamber base 120 and an annular outer wall 130 , and the annular outer wall 130 is enclosed on the air chamber base 120 to form the main air chamber 110 .

[0064] It should be noted that the air chamber base 120 and the annular outer wall 130 are integrally formed.

[0065] In some embodiments, the annular outer wall 130 may also adopt a detachable structure like the partition inner wall 140 , so as to facilitate the installation and disassembly of the mold and the air chamber structure when the size of the second air chamber 180 of the annular structure is small.
